Looming above passersby in Lisbon, Portugal, a gigantic raccoon protrudes from the side of a building. A close look at this multimedia street sculpture reveals that the raccoon's eyes are made from discarded tires, its arms from dented bumpers, and its claws from assorted metal scraps. This larger-than-life 3-D street mural is the creation of Artur Bordalo, a Portuguese artist whose unusual animal sculptures made out of garbage have attracted international attention. That's exactly what Bordalo wants: his goal is to raise awareness about the destructive effects of excess consumerism. To that end, the broad appeal of the animal world serves Bordalo's purpose well. By creating art with materials otherwise considered to be garbage, more and more artists are taking part in an environmentally conscious trend called "upcycling."
Which choice mosteffectively concludes the paragraph with a strong emphasis on its main idea?
B.For another of his sculptures, Bordalo chose to make an owl, the symbol of education and culture.
C.After the spectacle of the towering raccoon captures the interest of passersby, the sculpture's materials demand that viewers confront the waste products that are harming the natural world.
D.According to Bordalo, one of the technical challenges he faces in affixing mixed materials is that a particular glue may not work for both metal and plastic pieces.
Choice C is the best answer because it concludes the paragraph with a strong emphasis on its main idea. It illustrates how Bordalo's raccoon sculpture serves the artist's larger purpose of raising awareness about the destructive effects of excess consumerism.
